Changeset: 4d2e2182f9010107f402320dc37b059b4e2f5470
Author:	 Youness Alaoui <kakaroto at kakaroto.homelinux.net>

Branch:	 release-2.x.y
URL: https://hg.pidgin.im/pidgin/main/rev/4d2e2182f901

Description:

Adding new API for fetch_url with binary request.

The current fetch API uses 'strlen' to check the length of the request.
This is changed to use a request_len argument which allows for POST
requests to be sent with binary data.
